We left Resolute Bay in a Twin Otter for the 2 hour flight to the
McGill Arctic Reseach Statioin on Axel Heiberg Island. Our Station
is on the shore of Colour Lake at N79.41550 W90.75120 with an elevation
of 180m.
We ate lunch and had our first planning meeting with
Wayne Pollard of McGill University. After lunch we hiked down to
the active springs at the base of Gypsum Hill. We took a water sample
from one of the most studied of the spring sites here:
Little Black Pond. Located at N79.40409 W90.73309 elevation 19m.
See photo at right. Note the gas bubbles coming
up in the water.

We hiked along the White Glacier. Our destination
was a site that may be a dry relic of a former spring. We found
the site at N79.44386 W90.70168 elevation 343m. Samples collected
tested positive for carbonate here at the Station.

Today we hiked to the active springs. The group from the lower camp
(about 7 km away) came to the springs and we worked there together
this morning. We measured temperature. As previous data indicated
springs located without 10 m of each other have temperatures that
differ by 5ºC. Tomorrow the lower camp team will bring their
shallow seismic equipment and we will try to investigate the subsurface
structure of the springs to understand how such close-by springs
can have different temperatures.
Tuesday 29 July 2008
Our plan is to go back to the active springs at the base of Gypsum
Hill and do the seismic work.
